Is fast food making us depressed?

 Do burgers, sugary snacks and other unhealthy foods exacerbate the effects of mental illness? David Robson investigates the evidence, and discovers a surprising new idea to help treat depression.


The people entering Felice Jacka’s offices over the next few months will be in the throes of depression. She wants to help them – but her approach is unorthodox. Her team at Deakin University in Australia won’t be trying out a new cocktail of drugs. Nor will they be mulling over the patient’s childhood, their jobs, or their marital difficulties to help them cope with their problems. Instead, she wants them to talk about food.

If Jacka is right, changing their eating habits could be a key part of these people’s recovery. She has good reason to believe this; over the last few years, a series of striking findings have begun to suggest that fatty, sugary diets are bad for the mind, as well as the body. The result is a cascade of reactions in the brain that can eventually lead to depression.

Although the link is by no means proven, the fear that we are eating our way to depression is already prompting governments to take action. The US Department of Defence is now funding a trial that will deliver daily nutrient-rich food parcels to a group of former soldiers, to see if it can reduce suicide rates in army veterans. And at the start of this year, the European Union launched the 9m euro MoodFood project to further explore the way different nutrients may influence our minds. Certainly, no one is suggesting that a new diet should immediately replace existing treatments; Jacka’s volunteers will still be taking their medications as well as changing their eating habits. But if healthier eating can improve their recovery rate – or prevent some people developing symptoms in the first place – it would make for a simple, complementary way to help tackle mental illness.

‘Mind and body’

To grasp why your favourite dishes could be influencing your mental health, you first need to understand a strange aspect of the mind-body connection that first came to light 20 years ago. At the time, doctors were concerned that the stresses of poor mental health would weaken the body’s immune response, leaving them open to infection. Instead, they found the exact opposite was true; in people with depression, the immune system seemed to be going into over-drive. For instance, the blood of depressed people was awash with a particular type of protein, called cytokines, which normally lead to inflammation after illness or injury.

As the scientists pressed on, it became clear that this was a two-way process: not only could depression cause inflammation, but crucially, inflammation from other causes seems to be triggering depression. Some grounds for this link came from diseases that are known to send cytokines flushing through the body, like arthritis or cancer; patients often report depression before a diagnosis has even been made. “The people become depressed even before they know that they have cancer, and it ties in with the high levels of cytokines” says Michael Maes at Deakin University in Australia, who has pioneered work on the biological basis of depression.

More solid evidence comes from an ingenious experiment by Naomi Eisenberger at the University of California, Los Angeles. Her study involved injecting healthy volunteers with small fragments of the E. coli bacteria; it’s not enough to trigger food poisoning, but it nevertheless kicks the volunteer’s immune system into action, causing a release of cytokines. Although all the participants going into Eisenberger’s lab were reasonably happy and healthy, over the course of the day they began to develop many of the feelings you would normally associate with depression: their mood dipped and they were more sensitive to social slights, reporting feelings of disconnection and loneliness. And when Eisenberger asked them to play a computer game, for real cash prizes, the subjects appeared to take less pleasure in their wins than those who had not been injected with the fragment of bacteria – changes that were also reflected in scans of the brain’s reward circuits. An inability to feel pleasure, called anhedonia, is one of the most common symptoms of depression.

Evolutionary hangover

Lethargy during illness may have made sense during our evolution, says Eisenberger. “When dealing with infection, you would want to slow down, withdraw, and use your energy to recuperate instead of going out,” she says. But if, for whatever reason, the effects linger in the long-term, the results could be devastating; besides dampening your mood, inflammation can exacerbate oxidative stress in the brain. Oxidative stress, caused by toxic ‘free radicals’, could itself cause depression, since it can kill neurons, erode the brain’s long-range connections and disrupt the brain’s chemical signalling– sweeping changes that seem to come with long-term mental illness and may well contribute to the symptoms.

The upshot is that we may need to think about depression in an entirely new light – as a disease of the body as well as the mind. If so, many more things, besides life’s stresses, could put us at risk. Poor general fitness, smoking, and alcoholism are all known to increase an inflammatory response. And so, feasibly, could your diet: high fat and sugar levels – and the fatty tissue that results from it – are known to increase inflammation and oxidative stress. Conversely, certain nutrients such as omega-3 fish oils and minerals like zinc and selenium are anti-oxidants that can reduce inflammation and mop up some of the toxic chemicals, while boosting others that can help the brain to heal from damage.

Proving that this really can explain certain kinds of depression has been no mean feat, however. Although a few early studies had shown that people with depression often have a deficiency in nutrients like zinc, and that offering food supplements could improve their symptoms, the experiments were often poorly designed. “The whole area had been dogged by poor trials with small sample sizes,” says Jacka. As a result, it was difficult to know if the findings had just arisen by chance.  

Fish oils showed a positive impact on mental health (SPL)

But around 2010, three landmark papers caused more doctors to sit up and take notice. One took place in southern Europe, where doctors were charting the transition from the traditional Mediterranean diets, full of seafood, olive oil and nuts, to the fast food served in the rest of the West. Besides studying the risks of heart disease and diabetes, the scientists also looked at the 10,000 participants’ mental health. The differences were striking; those who lived almost exclusively on the traditional Mediterranean diet were about half as likely to develop depression over the period as those eating more unhealthy food – even when you control for things like education and economic status.

Around the same time, psychologists examining UK civil servants – in the famous ‘Whitehall’ studies – found exactly the same pattern; over the course of five years, people who regularly indulged in processed, high-fat and high-sugar foods were about 60% more likely to develop depression over the same period. Then Jacka confirmed the results with a further 1,000 Australian volunteers. Finally, the ball started rolling. “Over the following years we’ve seen an exponential growth in the number of studies,” says Jacka. Perhaps the best evidence came this year from the lab of Frank Hu at Harvard University, who directly traced the contributions of certain diet patterns with levels of cytokines, and depression; sure enough, foods rich in olive oil, leafy vegetables and wine reduced inflammation, and slashed the risk of depression by about 40%, compared to the ‘pro-inflammatory diet’, which includes sugary drinks, processed grains and red meat.

Getting well

Even your water supply might be having an impact, according to a recent study by Leigh Johnson at the University of North Texas Health Science Centre. She was recently studying the mental health of people in the western parts of the state – a rural population who still draw their drinking water directly from nearby wells. Crucially Johnson found that levels of the mineral selenium– an anti-oxidant that can combat inflammatory stress and which is also involved in brain signalling – in the well water had a direct impact on the chances of depression. People drawing water from wells with the highest levels of selenium, had about 17% lower scores on a standard measure of depression, compared to those in other areas. “That is very high,” says Maes. “It’s a really amazing result.”

As provocative as these findings are, the researchers will readily admit that there is still a long way to go before we can be sure of these conclusions. Eisenberger, for instance, acknowledges that certain foods can increase our inflammatory response, but she says it wouldn’t be as pronounced as the effects seen in her E. coli study. So it’s not clear that a poor diet would be enough to set you on the road to full-blown depression. And Johnson says that we should be careful not to over-generalise the results. “There are so many factors that can affect how depression could present itself in a patient,” she says. Your genes, lifestyle, and personal circumstances could all play a role. With so many different paths, it will be important to identify who would and wouldn’t benefit from better nutrition.

Some of these issues will be addressed in the next wave of studies. So far, the results have mostly come from observational studies watching people’s existing behaviour, but the researchers are now trying to actively change people’s diets in randomised trials, to see how it changes someone’s mental health. Success is by no means guaranteed; apparent correlations seen in observational studies can sometimes evaporate to thin air when you try more active measures to intervene in people’s lives – either because some other explanation lay behind the apparent effect, or because the interventions themselves are not practical. It is possible, for instance, that people at risk of depression may find it more difficult to change their eating habits, if they are already facing other stresses.

Surprise finding

Yet a chance finding by Charles Reynolds at the University of Pittsburgh offers some room for optimism. He had originally been testing a new form of psychotherapy in a group of older African Americans. “These people have a disproportionate burden of risk factors for depression,” he explains. Although they hadn’t been formally diagnosed with depression, his hope was that the therapy would offer some kind of protection against mental health problems in the future. As a comparison, half the group were given simple advice on how to eat more healthily – basic stuff on ways to eat delicious, nutritional meals on a low budget. Reynolds didn’t expect such a simple lifestyle change to heal his visitors’ minds – he just wanted to use it as a baseline, allowing him to measure the benefits of the ‘real’ therapy.

Two years later and it was clear that something very strange was going on. As expected, the people taking the psychotherapy had a reduced risk of developing depression; but so had the diet group, to an extraordinary degree; they were about half as likely to develop depression as you would expect for this kind of group, says Reynolds, and they reported a noticeable elevation in mood. “We were surprised, frankly,” says Reynolds. Importantly, these improvements came from minimal contact with the subjects – around 10 hour-long sessions across the two years. “That’s a remarkably short period of time to get the magnitude of effect that we saw.” His results were recently published in the American Journal of Psychiatry.

In line with Eisenberger’s earlier reservations, Reynolds points out that there are many reasons why the change in diet could have been so successful – and the potential anti-inflammatory effects are only one. Preparing more healthy meals is, in itself, a rewarding experience that boosts self-confidence, he says. “You might then believe that you can cope with other difficulties and respond adequately,” says Reynolds

Either way, the result has enthused Jacka about her own upcoming trial in Australia. Unlike Reynold’s study, she is trying to find out whether it can relieve the symptoms in those people already diagnosed with depression. Her subjects will have regular meetings with a dietician, who will advise them on the best ways to improve the nutritional value of their meals. Along the way, Jacka is taking blood tests to see if she can forge a more concrete link between components of the diet, levels of inflammation and oxidative stress, and the volunteers’ ongoing symptoms. If the visits to the dietician have a big enough effect on their recovery rate, she thinks it might then be possible to try out a dietary change as a treatment in its own right.

Reynolds points out that this kind of approach may appeal to people who feel uncomfortable with seeking other kinds of treatment. “Lifestyle changes may be more acceptable because they aren’t burdened by stigma – and they aren’t as expensive,” he says. Hu agrees that it holds a lot of promise: “Improving diet quality could not only reduce depression, but also the overall quality of life.”

For Jacka, a break in our love affair with fast food can’t come quickly enough. According to some predictions, nearly half of all Americans will be obese by 2030 – with countries across the world following similar trends. “If we add depression to the burden of illness that results from unhealthy diet,” she says, “no country can afford the cost.”

Dr Nathan Hughes – Visiting Marie Curie Fellow


The Centre for Adolescent Health is delighted to be hosting Dr Nathan Hughes who joins the MCRI for two years as Marie Curie Research Fellow, supported by a prestigious European Union scholarship. He is also Visiting Senior Fellow at the Melbourne School of Government. Nathan is based in the UK as Senior Lecturer in the School of Social Policy at the University of Birmingham.

Whilst in Melbourne, Nathan is undertaking a programme of research concerned with the application of biological and neurosciences to law and social policy. In particular, he is interested in explanations regarding patterns of offending amongst young people with neurodevelopmental disorders, and their implications for policy and practice within the criminal justice system. Nathan’s previous research has highlighted consistent evidence of a high incidence of neurodevelopmental disorders amongst offending populations, particularly those in custodial institutions. It identifies a range of difficulties with youth justice practices, including in needs assessment and responsive, specialist intervention.

By engaging with experts across the Campus, Nathan hopes to inform a range of practical developments in policy and practice. As he says, “Whilst research consistently demonstrates that youth justice systems continue to punish young people for the risks and vulnerabilities associated with their neurodevelopmental difficulties, advances in biological and neurosciences have the potential to inform practices better able to meet the needs of this vulnerable population. This offers grounds for optimism in the future development of services and support based on our improved understandings of neurodisability.”

“Improvements in screening and assessment can ensure earlier identification and intervention. Training of key staff can ensure recognition of the challenges facing those with neurodisability in engaging with the youth justice system. Interventions that respond appropriately to the needs of these young people can ensure more effective and cost efficient support to prevent the onset of anti-social behaviour and break a common cycle of persistent and serious offending.”

Welcome to Associate Professor Felice Jacka


The Centre for Adolescent Health warmly welcomes Associate Professor Felice Jacka who will be spending time with us in an honorary capacity through the Murdoch Childrens Research institute.  Felice is a Principal Research Fellow at Deakin University, who also holds an honorary position at the Department of Psychiatry at The University of Melbourne and the Black Dog Institute. She is recognised as a leading expert regarding the association between diet quality and the common mental disorders, depression and anxiety. She is president of both the International Society for Nutritional Psychiatry Research (ISNPR) and the new Australian Alliance for the Prevention of Mental Disorders (APMD).

Felice’s ongoing program of research focuses on health behaviours, particularly diet quality, as risk factors for mental disorders. It incorporates a broad range of epidemiological and public health investigations, with extensive partnerships and collaborations in Australia and elsewhere involving the acknowledged experts in the field of psychiatry, psychology, medicine and public health. Her program spans the spectrum of research, comprising detailed investigations of biological mechanisms and drivers of the relationships between lifestyle and mental health, such as the gut microbiota and immune system, through to the development of clinical and community based interventions. It aims to yield new knowledge that can be readily translated to inform public policy. Her primary goal is to develop a coherent public health message and effective, best-practice strategies for the universal primary prevention of the common mental disorders.

Felice’s engagement at the Centre builds on the collaborative relationship that she developed with Professor George Patton and the CATS study, from which she appreciated that there are wider opportunities for collaborative research. She says, “I am particularly drawn to the wealth of expertise available at MCRI in both the biological sciences and psychiatric epidemiology. Most importantly, with my prevention hat on, I am increasingly interested in early life exposures as important modifiable targets for preventing mental disorders across the life course”. How is Felice finding it? “It has exceeded my expectations. The environment is cheerful, friendly and collaborative and there are so many talented researchers with whom I can share my interests!” Felice is interested in the wider social and economic aspects of population mental health. “I believe that working at the Centre for Adolescent Health will enable me to develop key research projects that relate to each of these areas”.

Congratulations to Dot Henning

Dots front page IJSA March 2014Dot Henning is congratulated for her efforts in leading new research into the sexually transmitted infection Mycoplasma genitalium in young people experiencing homelessness who access care at the Young People’s Health Service (YPHS) that is run by the Centre for Adolescent Health.

The study offered STI screening (Chlamydia, Gonorrhea and Mycoplasma Genitalium) to asymptomatic young people accessing primary level care at YPHS for health concerns other than sexual and reproductive health. Of the sixty young people tested, 8 tested positive for Mycoplasma Genitalium and 10 for Chlamydia, and three testing positive for both. Mycoplasma Genitalium is increasingly recognized as an important STI, and this study provides important data to the prevalence of this STI amongst marginalized youth. Additionally, this study highlights the complex health needs of this population, and supports the need for comprehensive primary health care.The research findings have just been published in the March 2014 edition of the International Journal of STD & AIDS with the article gaining a mention on the journal’s front cover. Dr Peter Azzopardi (Research fellow, Centre for Adolescent Health), Clinical Nurse Consultant Donna Eade and Youth Health Nurse Alison Langstone (previously) from YPHS, and Dr Alex Marceglia and Nurse Practitioner Alison Bean-Hodges from the Sexual Health Service at the Royal Women’s Hospital provided valuable assistance with the study.

Free on-line learning modules on AYA cancer


The Centre for Adolescent Health in collaboration with the University of Melbourne and ONTrac at Peter Mac Victorian Adolescent and Young Adult Cancer Service is celebrating the launch of two online learning modules on cancer care for adolescents and young adults (AYA). The modules have been created using a novel method of online learning developed out of Harvard Medical School known as spaced education, where courses are comprised entirely of multiple choice questions and answers delivered to the learner’s email inbox at regular intervals. The approach is backed by a strong evidence base and has been found to improve knowledge acquisition, increase long-term knowledge retention and effectively change behaviour.

 “Learners receive two questions every other day, which can be accessed via desktop computer, tablet or mobile phone,” explains Project Coordinator Sam Van Staalduinen. “You receive immediate feedback on your responses along with corresponding evidence-based information, key messages and freely available resources. It’s about delivering short bursts of information at a time and place that suits the learner- the approach allows people to enhance their understanding of issues relating to young people with cancer and develop greater confidence in working with this unique patient group through a fun approach to learning that only takes a few minutes a day.” Upon completion of each module, learners also gain access to a website containing all of the information and resources for future reference.

 Cancer Care for Adolescents and Young Adults Part I and II are freely available and aimed at clinical and non-clinical professionals working with young people with cancer, or anyone with a professional interest in the field.
